Hogwarts Card Drawer

After Kronos finished class, he and Draco came to the auditorium for dinner. The food is still the same, potatoes, beef, oatmeal, the same old three that will never change.

It has to be said that Hogwarts' owls are still very efficient. The owl letter that Ron just sent in the morning received a reply at noon. Just another Howler letter.

"It's all your own fault that your wand is broken." Mrs. Weasley's voice, amplified hundreds of times, roared in the Great Hall.

At the Gryffindor table, Hermione showed them her Transfiguration homework. Turn a beetle into a beautiful button. Ron's mood still didn't improve.

"What's the class in the afternoon?" Harry hurriedly changed the subject.

"Defense Against the Dark Arts with the Slytherins," said Hermione quickly.

"Huh?" Ron wanted to grab the timetable in Hermione's book, and said in surprise, "What is this? Why are there a bunch of circles and triangles drawn on it?"

"I think it should be the paper of Chronos' magic circle class?" Harry glanced aside and said that he had seen the magic circle made by Chronos in the Daily Prophet. The pattern above is just some circles.

"You don't really want to take that... Kronos' magic circle class?" Ron asked in disbelief.

Hermione snatched the paper back, blushing annoyed.

"Ron, if you think you are greater than Dumbledore, then you don't need to take any magic circle classes. You know, even Dumbledore asked Chronos to teach at Hogwarts." After Hermione finished speaking, she picked up the books on the table and hurried away. In fact, she was not in a very good mood, because she couldn't understand several geometry questions on the paper.

"Is she crazy? Did I not let her go? I just asked kindly!" Ron looked at Hermione's back and looked at Harry suspiciously.

Harry shook his head, indicating that she didn't know either. To be honest, he also wanted to take a paper, but he didn't go because of his friend Ron's feelings.

As for Chronos, he left the auditorium with Draco and the others after dinner. They parted at the foot of the stairs, and Chronos did not follow them back to the Slytherin common room. In fact, he didn't need to go back, the professors at Hogwarts all had their own lounges. Dumbledore would not take away such powers from him.

Kronos came to his office on the third floor, where he got inspiration from the group of students that morning. Wanted to write a textbook on geometry in Muggle mathematics. Just write some basic theoretical knowledge of geometry into a book, and then use the copy spell to copy it hundreds of books. Finally, buy it for students, maybe it can become the designated textbook for Hogwarts. This is another handsome income.

"Bang, bang, bang," as Kronos was thinking, there was a knock on his office door.

"Please come in." He didn't know who would come to him.

Looking up, he saw that it was the small, shaggy-haired boy he had seen at the induction ceremony last night. He stood there staring at Chronos. The sweat on his brow showed his inner unease. He held tightly in his hand the normal camera used by people in the Muggle world.

"Hello, Professor Slughorn. I'm—I'm Colin Creevey." Almost out of breath, he took a tentative step forward. "I'm Gryffindor House. Do you think - would you - let me take a picture?" he said hopefully, holding up his camera.

"Take a picture?" Kronos was stunned for a moment, and then he reacted. In the second book, the boy named Colin Creevey is Harry's little fan. Chasing and taking pictures of Harry every day caused Harry a lot of trouble. But the camera in his hand helped him escape the attack of the basilisk.

Speaking of the basilisk, Kronos thought of that diary. Kronos thought for a while,

He still believed that the diary should have been lost during the fight at Lihen Bookstore, and he was patronizing to watch the excitement at that time. No attention was paid to the cauldron in Ginny's hand at all. As for the basilisk in the secret room, Kronos looked at the contract card in his system space. Kronos now has enough mana to use it. Although he already has Toothless, he still wants to keep the basilisk in his pocket.

"But... can it be?" Colin stared at Kronos for a long time, thinking that he was unwilling.

"Ang?" Kronos felt uncomfortable when his train of thought was suddenly interrupted, but he still smiled and asked Colin to take some handsome photos of himself.

"By the way, Colin. Could you please call Mr. Filch over for me?" Chronos stopped Colin who was about to leave.

"Of course, Professor Slughorn." Colin seemed very excited to be able to help the famous magister in the wizarding world. He is very happy.

After a while, the door of Chronos' room was knocked again, and Chronos knew that it was Filch outside the door this time.

"Come in," he said.

Sure enough, Filch's face appeared from behind the door.

"Professor Slughorn, are you looking for me?" Filch smiled at Chronos, his face full of flattery.

"Oh, yes. Mr. Filch, thank you both this morning and last night," Chronos said.

"You don't have to thank me, Professor Slughorn. This...this is what I should do." Filch lowered his head excitedly, he was a little flattered.

"Come on, Mr. Filch." Chronos laughed. Filch's respect for him was a bit out of place. "As you can see, I've run out of paper to write on. So I need to ask you to get me some new paper."

"No...no trouble, it should be, it should be." Filch said, and hastily left Kronos' office. When he left, he still closed the door gently.

Kronos smiled, he was now thinking about the geometry knowledge his teacher taught him when he was in school in his previous life. It's just that what I learned in my mind seems to be returned to the junior high school math teacher. He is only glad that the magic circle only uses plane geometry. If it is three-dimensional geometry, Kronos is really dead. The first famous magister in the wizarding world can only teach wizards to draw pictures, but not theoretical knowledge.

Fortunately, I only need to call them some simple magic circles, and I only need to write something about the properties of triangles and the definition of circles.

After a while, Filch came back. He just pushed the door open, and with him was a large pile of writing paper in his arms.

Chronos wrote on the first piece of paper: "Five years of drawing, three years of simulation".
